My point is that there are no 'genuine consequences'. We are told that supposedly there is selection and that the predictive power is nearly perfect and everyone relies on solely genetics to do everything; and yet, we do not see a world which reflects such effects at all. This worldbuilding does not make sense from a scientific perspective. Instead, what we see is a world in which you have extremely cheap sequencing in a panopticon and a caste society based on seemingly-random arbitrary discrimination with no actual consequences to any supposed inferiority or superiority*, akin to the classification of supposedly-objective 'classes' in North Korea where everyone is finely graded on hereditary loyalty to the elites but could be knocked down a rung at any time for suspected disloyalty.

(My headcanon is that the esoteric story of _Gattaca_ is that none of the supposed embryo selection or valid/invalid screens exist at all, any embryo selection is just ordinary IVF quality control for aneuploidy etc, there is only cheap universal sequencing developed by a totalitarian police state like the CCP (see: Zero COVID testing), and the classification exists to manufacture distinctions and divide families and punish/reward elite supporters; the Freemans were some lower 'wavering' class, grouped with religious minorities, as indicated by their dissenting 'natural' birth, and so they earned a valid vs invalid split within their family. It makes more sense than the actual story, anyway.)

* I've remarked elsewhere that _Gattaca_ is an example of how movies with a message tend to fail by loading the dice too heavily for one side, removing any 'moral dilemma', and it is no exception: we never see any evidence that Vincent is doing anything wrong or that he shouldn't go on the space mission. In fact, given his methodical penetration, high competency, motivation, and extraordinary success at getting into the mission, he shows that he should be selected for his moxie and chutzpah. So what _Gattaca_ should have done was to make the ending Vincent suddenly clutching his heart from the shock, and fade to black.
